YouTube video showing Rihanna dash off stage causes health scare

Melbourne, November 8 : Rihanna, who is trotting the Australian continent with fellow singer and beau Chris Brown, sparked health concerns after she was seen rushing off stage during a performance.

The 20-year-old was speculated to have collapsed while performing her hit track 'Umbrella' with Brown at a Sydney concert as part of her world tour.

A YouTube video showed a part of the incident and the paramedics were said to have been called for.

However, the singer's spokesman denied any possible cause of worry blaming her rush to a hot Sydney night and dehydration.

"It was very hot at the venue, so after Rihanna's set was over, she went off stage to sit down, catch her breath and have some water," News.com.au quoted a rep as saying.
